Whistleblower Edward Snowden has weighed in on a debate between MSNBC host Joe Scarborough and writer Jay Caruso over the controversial GOP memo that was made public last week.

On Friday, the House Intelligence Committee released the memo, which was drafted by the staff of Republican Representative Devin Nunes. It alleges the FBI and Department of Justice did not provide adequate information to a judge when they sought to renew a court warrant for surveillance of Carter Page, a foreign policy adviser for the Trump campaign.

In an unlikely debate on the memo’s release, Scarborough found himself on the receiving end of a tweet from Snowden, the former National Security Agency contractor who sought political asylum in Russia following his leaking of documents that exposed the breadth of the NSA’s mass surveillance program.

Sharing a National Review editorial, Scarborough tweeted on Sunday: “A disappointing @ NRO editorial trying to explain away Trump and Nunes’ war on the Justice Department and FBI. It even applauds exposing the FISA process for a partisan memo that only hurts Trump’s cause. What a long way from the #NeverTrump cover.”

Caruso hit back at Scarborough’s tweet: “This is a mischaracterization of what they wrote. The key paragraph says all the information should be released so the public knows what happened.”

Not to be outdone, Scarborough replied: “‘All the information should be released....’ My God. You now embrace Edward Snowden’s reckless approach toward national security matters like FISA? How illuminating.”

After his name was dragged into the debate, Snowden himself responded to Scarborough, apparently shutting down the debate, Mediaite reported.

“Dear Joe, with respect, that "reckless" approach led to the largest reform of unconstitutional domestic surveillance since 1978, and the 2014 Pulitzer Prize for Public Service journalism. If that's what recklessness looks like, we could use a hell of a lot more of it,” he wrote.
